Keysight N9041B UXA Signal Analyzer

Option 5CX, 2Hz – 110GHz

The Keysight N9041B UXA Signal Analyzer configured with Options 5CX, H1G, and RT2 provides a complete high-performance solution. With option 5CX, the analyzer covers 2 Hz to 110 GHz, while option H1G enables up to 1 GHz of analysis bandwidth. Option RT2 adds real-time spectrum analysis with 2 GHz real-time bandwidth and 100% probability of intercept for signals ≥3.84 µs. This integrated configuration achieves a displayed average noise level as low as −174 dBm with a preamplifier, amplitude accuracy of ±0.25 dB, and phase noise of −127 dBc/Hz at 1 kHz offset, making it suited for wideband 5G/6G, satellite, radar, and electronic warfare applications.
